I can't think of any companies that after two model replacements would still be offering the kits for the older units. You might get lucky and find one left over some where, but don't count on it!

If you wish, you can simply plug it into the existing hydraulics, using the correct couplers. Then, when you pull the proper lever, and perhaps hold it there with a bungee cord or something, the fluid will flow thru the backhoe valve. This works for me. I already had a three-spool valve added, from a power beyond, but didnt have anymore room for anymore couplers or anything. So I put on the right nipples and plugged it into the existing couplers. When I found out the correct flow direction, I marked the couplers with colored zip ties.

I HAVE A 755JD WITHOUT THE POWER BEYOND KIT. I DON'T THINK IT'S AVAILABLE FOR THIS MODEL FROM THE DEALER ANYMORE. IS IT POSSIBLE OT HOOK IN TO THE HYDRAULIC SYSTEM TO OPERATE A BACKHOE

Please turn you caps lock off... I added a power beyond to my JD 650 tractor. This tractor has power steering, and a loader installed so what I have drawn up, might not work for you. The local JD was no help. The 755 is newer and should have something at the dealer. I can send you an email with the two drawings I have of mine, that I made. It requires you to take off a hose on the 3 point, series out and back, you also need to install a tank return line. After you do the mod, you must then install a hose jumper between the Out and In hoses, so your system still works, after you remove your remote equipment.
